With the newly released SAP 9.1 PL13 SAP unfortunatly have made a bug that Mandatory Fields are affected by :-(
What is the issue?
If you are running SAP 9.1 PL13 (no other patch so far is affected) and you have mandatory fields on line level in any Sales and Purchase document the bug prevent B1UP to check these (will allow users to continue despite the fields are empty)
I'm affected. What to do?
We have create a 2016.06.2 hotfix release that fixes the issue. You can download it here: http://www.boyum-it.com/sbo/Beta/B1UP2016_062_SBO9.zip
B1UP 2016.08 will be the first full release to include the workaround.
What about the future?
We will report the issue to SAP and hopefully they will fix it in an upcoming release. Until then the hotfix is in place. We will update this note once we have feedback from SAP.
