Issue with Zero Net Value in Sales Order After Updating Billing Plan Using BAPIs

[jay_dalwadi]

Hi Experts,

We are currently facing an issue with our sales order creation process. Here's the sequence of BAPIs we are using:

1.DIPCOL_COLLECTIVE_RRB
2.BAPI_SALESORDER_CHANGE
For billing plan updates, we are using:
3.SD_VBKD_READ_WITH_VBELN
4.BILLING_SCHEDULE_READ
5.BILLING_SCHEDULE_SAVE

With this logic, we are able to create and update sales orders, and the billing plan updates perfectly. However, the sales orders are being created with a zero net value. If we exclude the billing plan-related BAPIs (SD_VBKD_READ_WITH_VBELN, BILLING_SCHEDULE_READ, BILLING_SCHEDULE_SAVE), the net value of the sales order calculates correctly.

We have already raised an OSS message, and SAP replied that the FM SD_SALES_BILLINGPLAN_CHANGE is not released. They suggested discussing the issue with an other SAP consultant or making use of the SAP Community.

Has anyone encountered a similar issue or have suggestions on how to resolve this?

Any help or guidance would be greatly appreciated.
