I have to do flat rate billing for one implementation project , I have configured main/sub transaction and also assigned it to internal main sub transaction .
corresponding entries have been maintained in EK02 and EK01 but when I am pressing F4 button in DST/CST , nothing is populated .
When I am entering sub transaction manually , getting different types of error . (For example -
The internal transaction 0051 is not assigned to an external transaction.
Sub-transaction 0020 does not exist in table TE305 for division 02 )
I am not able to understand what is missing here. Could you please provide your expertise .
Please find the screenshot attached herewith .
Any help will be highly appreciated .
Thanks & regards,
