Hi All,

i would like to know the transaction code for create/ migrate data for,

1. GL FINANCIAL TRANSACTIONS / ACCOUNTING DOCUMENTS

2. Direct Invoice

3. Payment document (AP)

4. Asset Transactions

5. Bank Recon - Bank Clearing account

6. Bank Recon - Bank account

7. AR accounting document

now im doing migration for above transactions,

can i use a single t.code / templete to migrate

data. bcoz im using FB03 t.code (FB03 u2013 Display Document)

for displaying.

so my query is that, if displaying FB03 means any other t.code

for all to migrate/create.

is possible, using one t.code to migrate data???
