How can we trigger external workflow API for sales order approval

[former_member727011]

Hello Experts,

We have sales document approvers in external system, and approval process is completed using workflow in external system.  In S4HC I completed the setup of approval request reasons and flagged the reasons as 'External Workflow'. I also updated the BADI to populate the correct approval reason. When order is created status is changing to 'In Approval' with proper reason. But now, how can I call the external workflow API? Is there a BADI where I can trigger this? Any input is greatly appreciated.

Regards,

Sam

Hi slan6,

In order to determine a sales order relevant for external approval, you can use the Business Add-In (BAdI) Set Approval Request Reasons for Sales Documents (SD_APM_SET_APPROVAL_REASON). You can find this BAdI in the Custom Fields and Logic app under Custom Logic, using the Sales: Sales Document business context.

I recommend you to read the following documentation:

Sales Order Header: https://help.sap.com/viewer/03c04db2a7434731b7fe21dca77440da/LATEST/en-US/28d644581efca007e10000000a...

Hope this helps.

Hello Arturo Montes de Oca,

Thank you for your reply.

I am using BAdI Set Approval Request Reasons for Sales Documents (SD_APM_SET_APPROVAL_REASON) for setting the approval reason and order is going into approval process. Now my issue is triggering the external system workflow. By the time this BADI is triggered, sales document is not created and sales document number is not available in this BADI.

So my question is - is there any process where I can trigger external workflow? or am I missing something here?

Regards,

Sam

Hi slan6,

To use the APIs, you first need to create a communication arrangement based on the communication scenario.

On the SAP API Business Hub, check the Details tab of an API to see which communication scenarios it is part of. You can also search for a communication scenario to see which APIs it contains.

To Release or Reject Sales Orders in Approval, the communication scenario Sales Order Integration (SAP_COM_0109) contains the API Sales Order (A2X).

Please find relevant documentation here:

• Communication Management: https://help.sap.com/viewer/0f69f8fb28ac4bf48d2b57b9637e81fa/LATEST/en-US/2e84a10c430645a88bdbfaaa23...

• API Sales Order (A2X), check the API References tab, select the Service Operations option and you will find the invoke action for reject/approval request: https://api.sap.com/api/API_SALES_ORDER_SRV/resource

• FAQ for Sales Order Management and Processing: https://help.sap.com/viewer/03c04db2a7434731b7fe21dca77440da/LATEST/en-US/7fac58721052484c8fe785be46...

Best regards,

Thank you Mr. Arturo Montes de Oca. I thought there is a some easy way that I am missing to call an external workflow API directly. Looks like only solution is by using output setup and API Sales Order (A2X) setup and some middleware.

Thank you for your input again.

SAP recommends to only change approved sales documents in exceptional cases. Once a sales document is approved, subsequent processes like deliveries and billing are triggered. Keep in mind that you will have an impact on these subsequent processes if you change any approved documents.

While SAP strongly recommends that approved sales documents should not be changed there is an Emergency fallback in that the approved sales documents can be changed via the VAxx frontend WEBGUI transaction Apps such as Change Sales Orders (VA02)
