Orchestration with multiple distribution items for Standard Invoice Entry

Hello,
I'm working on a requirement to create Orchestration for the Standard Invoice Entry process; the application flow is as follows:

P03B2002 Form A —> P03B11 Form A —> P03B11 Form C —> P03B11 Form A --> P03B2002 Form A

When It comes to P03B11 Form C (G/L Distribution), we need to add multiple line items. I was getting error 088R, and I followed the solution provided in the document:

https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=301109579720154&id=2711608.1&displayIndex=1&_afrWindowMode=0&_adf.ctrl-state=pfix65ou4_235#SYMPTOM

This works fine if I have only one (1) distribution line. However, as per requirement, we can have multiple distribution lines, and the orchestration is failing for multiple distribution lines.
