Internal Main and Sub Transactions

[Former Member]

Can the experts please explain what is the use of internal main and subtransaction?

also if we allocate an external sub transaction to this internal sub transaction, this subtrnsaction cannot be selected while creating rates.( during selection of DST and CST in rate steps). why is it so?

Hello,

Internal Main and Internal subtransaction are used for programmatical identification. we link the internal transactions with External transactions so for to our usage.

we mention external subtransactions at rate.

They are in the program to determine the main transaction defined by the customer.

These are provided by SAP. These are used in source code of SAP. You cannot either create/change/delete these MT/ST.

also if we allocate an external sub transaction to this internal sub transaction, this subtrnsaction cannot be selected while creating rates.( during selection of DST and CST in rate steps). why is it so?

You allocate SAP provided MT/ST to External MT/ST.

Not all the MT/ST in Invoice/bill creation are config driven..most of them are standard SAP program driven so you cannot use them

Hope this helps

Dear Narendar,

Is it that we don't have to make any changes to the internal MT/ST?

For billing piurpose is it only external subtransaction are only used? Pls clarify!

Hello,

we dont touch internal main and internal sub transactions.we only mention external transactions.

In many processes, main and sub-transactions can influence automatic account determination.

An internal main transaction can be assigned to the main transaction, and an internal sub-transaction can be assigned to the sub-transaction.

Internal transactions control the way in which application-specific processing programs run.

"Internal transactions control the way in which application-specific processing programs run."- can you please explain more on this?

also iam not getting one of the external ST when i press f4 (DST,CST)during creation of rate type. what would be the reason for this?

To elaborate, if you take Returns program <<using FP07>>, the document posted during return process shall have MT = 0070 & ST =0010.

This is driven by Standard SAP program <<SAP program holds what all MT/ST it has to assign for Returns program>>. So these are nothing but Internal Transactions.

Similarly all Standard SAP programs shall have identified MT/ST.

also iam not getting one of the external ST when i press f4 (DST,CST)during creation of rate type. what would be the reason for this?

Check whether you have maintained values in tables TE305 <<use SM30 for Config path>>, EK01 & EK02.

Hope this is clear & helps.

For any application, it has to do several tasksi.e identification of receivable account,and what to do next.....nest...next.

Program:it is series of sequential flow of steps.

program logic is written by sap for the applications.

in this application , we are using internal transations for to identify related activities i.e to identify the external transactions..

go through this path:

spro>financial accounting>contract account receivable andpayable>basic functions>posting and documents>document>maintain transactions for isu/istmaintain transactions for billing

Maintain main and sub transactions for your company code ,division,main transaction and subtransaction.

If u have any querries please let me know...
