Why I can not delete Import parameter?

[Former Member]

Hi All,

From SAPNote 775548

https://websmp230.sap-ag.de/sap(bD10aCZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=775548

I want to change the Interface Function Module 'FMRE_DOCUMENT_REVERSE' follow Note 775548

1. Delete Import parameter I_F_ACCREV

2. Create NEW Import parameter I_ACCREV

After apply SAPNote 775548 Into my SAP system.

I registered object for develop this fuction module already, I could create NEW Import parameter I_ACCREV but I could not delete Import parameter I_F_ACCREV and message show 'unpermitted modification' when I deleted parameter I_F_ACCREV.

I made it at client 000 of DEV and SAP version 4.7

Thanks for suggest,

try this workaround : set checkbox "optional" of old parameter

so you don't have to delete it, but you don't have to call it neither
