SC for service item: value limit created in PR

Hi,

I'm having a really rare issue here. Whenever I order a SC for a free text service item, the PR created in ERP Backend is coming with a fixed limit value not included in SRM SC. For example, I create a SC for 1USD and the following PR created is for 1000USD because of the value limit automatically created.

I'm finding this issue in my QAS System and not in DEV. I checked if any inforecord or conditions exists but I didn't find anything.

I'm implementing SRM 5.0 (SRM Server 5.5) with ERP 6.0 as Backend.

Any thoughts?

Thanks

Nicolas
