Release Summary
This update fixes date calculation errors in Simple MRP and the lead-time calculations when Business Central runs in a non-English language, such as German.
Bug Fixes
Move and lead-time date calculations now work in all Business Central languages
The Simple MRP move-date calculation and the lead-time calculations could stop with an error saying the date formula must contain a time unit when Business Central ran in a non-English language, such as German. Lead times of 1000 days or more could also give an invalid result, whatever the language. These calculations now work in every language and for any lead time length. The fix applies to the Calculate Simple MRP, Calculate Rolled up Lead Time and Rolled up Lead times actions on the Reverse Planning - Simple MRP page, and to the Calculate Rolled up Lead Time action on the Item Card.
Why it matters: Planners can move demands and calculate lead times without errors, whatever language they work in.
