Questions Transaction were not created during the allocations

I wish I could help, but it's been a while since I used allocations.

Teckla, 

Look at the settings under Allocation Rules and the tab Allocation Settings.  I recommend reading the help file in Acumatica regarding this before making changes.  However, I remember this happening for me a long time ago.  I believe it was when a Time Activity was not COMPLETED, as I was trying to allocate employee burden calculations on a Project.  Once I changed the Status on the Time Activity to COMPLETED, the allocation ran with no errors and produced the desired results in my Project Balances.
