I am unable to post Journal Entry, it hasn't happened before, and now Navision is posing an error message "You must specify Source Code G/L Entry to CA in Cost Accounting Setup Primary Key="." (Image as below)
It seems that I can resume posting Journal Entries after changing to this configuration: Source Code G/L Entry = SALES. (image as below)
My source code used to be empty before the error message popped up. I am just concerned that this SALES configuration will have an impact on the functions in Navision which I do now know. Please help.
