Fixed indicator set on PR after source of supply assignment

[0021962210]

Hello Experts,

We are facing the issue, that the fixed indicator on a PR is set (for PR's generated by the MRP run) once a source of supply is assigned. In our business process, this is not desired.

In this note: https://launchpad.support.sap.com/#/notes/1721189

I found that the fixed indicator should be set when one of these fields is changed manually:

• Purchase requisition quantity (EBAN-MENGE)
• Delivery date of the item (EBAN-LFDAT)
• Purchase Requisition Release Date (EBAN-FRGDT)
• Storage location (EBAN-LGORT)
• Goods receipt processing time in days (EBAN-WEBAZ)

Since vendor is not one of them, it seems like the behaviour is not correct? Does anyone know if this can be changed, either via a standard or custom solution? We are on S/4 1909.

Thanks,

Jasper
