Brief overview about the support work

In the Product Support, we always start the analysis with some basic checklists from past troubleshooting experiences. This means, firstly we are checking the received error messages, or the behavior and if it is a typical issue in the system, then the solution can be simple.

Sometimes, in case the system raises an error message, or the behavior is a well-known issue, even a remote connection might not be needed.

If the reported issue / behavior is not a common problem, then to avoid any misunderstanding as well as to speed up the analysis, a step-by-step document and the opened R/3 and HTTP connection is necessary.

In this post there are 2 separated sections, which contains

  1. typical issues and error messages

  2. good-to-know places / help for the analysis

Typical issues during the transfer

Some of the typical issues / malfunctions during the transfer can be checked in the BBP_PD transaction, but some of them has only a well-known error message

1.       Different Follow-on document created during Classic transfer

When a Purchase Order is created instead of Purchase Requisition, the first thing to do, is check the SRM system’s customizing. In this case, you need to check the Node under the SPRO > SAP Implementation Guide > SAP Supplier Relationship Management > SRM Server > Cross-Application Basic Settings > Define Objects in Backend System (Purch. Reqs, Reservations, Purch. Orders).

Under this Node, the system determines the Follow-on document type based on the Product Category and the Purchasing Group. Please always avoid using the * characters for both Purchasing Group and Product Category. For more info, please check the ‘1173815 - Purchase requisition instead of purchase order’ SAP Knowledge Base Article and the Determination of the follow-on document type - https://wiki.scn.sap.com/wiki/x/j4I2FQ SAP Wiki page.

2.       Shopping cart XXXXXXXXX: Error creating the follow-on document

During the classic transfer, the system could not create the Follow-on document in the ECC and the ‘Shopping cart XXXXXXXXX: Error creating the follow-on document’ error message is shown in the RZ20 transaction.

This happens, because the number ranges are not correctly maintained in the SRM and in the ECC environment.

To solve the behavior, please go through the ‘2669810 - Shopping cart XXXXXXXXX: Error creating the follow-on document’ SAP Knowledge Base Article.

3.       ME 218 External document number XXXXXXXX already assigned

During the transfer, the ME 218 error message raised by the system.

This happens, because the number ranges are not correctly maintained in the SRM and in the ECC environment. To solve the behavior, please go through the ‘2774653 - Shopping cart XXXXXXXXX (Type YY XXXXXXX): ME 218 External document number XXXXXXXX alread...’ SAP Knowledge Base Article.

4.       Splitting problems: Shopping Cart creates more than one follow-on document

The common root cause of this issue is that, one of the Shopping Cart’s item contains a Preferred Supplier and based on the standard grouping / splitting logic, the one item will be different from the other which results in a separate Purchase Order.  The preferred supplier can be determined through  a custom BAdI logic, or it can come from the Catalog.

Please also note that in older system design, the Plant was a splitting criterion, this was changed to Plant's country. If you need more info about this, you can go through the Item grouping of follow-on Purchase Orders from Shopping Cart  - https://wiki.scn.sap.com/wiki/x/CwIIFQ SAP Wiki Page and the  ‘2373866 - Splitting Criterion for PO Should Not Include Plant’ SAP Note.

5.       ORDERED_PROD leading zero issue

In this scenario, when you check the BBP_PD transaction you can see that the Ordered_Prod value has a lot of zeros before the product number. The field can be seen in the main screen of the BBP_PD transaction under the Items section and inside the item details under the CRMD_ORDERADM_I table.

Screen Shot
ORDERED_PROD leading zeros in BBP_PD

In this situation, the “BBP_PD 275 - View of Product &1 or plant-storage location combination does not exist” error message is raised by the system. When the system raises this error message, the customizing should be checked in the SRM and in the ECC environment as well based on the SAP Knowledge Base Article ‘1789033 - Product &1 does not exist in plant &2 or it has been flagged for deletion error in Shoppin...’.

6.       Error in currency conversion from [currency1] to [currency2] in transfer of SC [SC number]

Screen Shot
Error in currency conversion

If the system raises this error message during the Follow-on document creation, there are two possible ways to solve this.

  1. For the inverse conversion, mark the flag "XINVR" at Rate Type.

  2. Or for using the reference currency with 2 step conversion, enter a reference currency.

You can also check the ’1829448 - Currency conversion problem when the Shopping Cart has different currency than the Purchas...’ and ‘783877 - Currency translation: FAQ’ SAP Knowledge Base Article.

7.       BBP_SOC_APP_01 007 Price could not be translated to standard currency

This error message appears in RZ20, when the user tries to create a Purchase Requisition from the Shopping Cart, but the item currency is different than the assigned vendor’s currency, or the currency conversion rate is not set correctly in the SRM system.

To solve such problems, please go through the ‘2644289 - Price could not be translated to standard currency - error message during shopping cart tr...’ SAP Knowledge Base Article.

7.       Other useful Shopping Cart status issues:

From a Support perspective, the easiest way to trigger a Shopping Cart transfer analysis is when a Shopping Cart has I1112, “Error in transmission” status. In such cases, we can simply retransfer the given document by debugging and check what was failing during the transfer.

In case the Shopping Cart is stuck in transfer process status I1111, the document can be retransferred only with the BBP_SC_AUTO_RETRANSFER standard report.

In any of the above Shopping Cart statuses, you can considerably speed-up the support process by creating two-three Shopping Carts in “Saved” status, that is, without triggering the approval process and transfer. That way, our Support Engineers can immediately trigger transfer on those Saved documents. For this, our engineer will only need an R/3 connection to the affected SRM system.

BAPI issues:

The standard system is capable to create BAPI test data in the ECC environment. During the RFC call, the system will capture the received data from SRM and store it in a test data. During the analysis, this test data can be run multiple times in testrun, without creating or changing anything in the ECC system. If you need help to create the test data, please go through the Creating test data for ECC backend purchasing documents - https://wiki.scn.sap.com/wiki/x/cIQpFg SAP Wiki page.
