How To Fix F4749 - Caution: Before reconstruction check IMG settings (see long text)

F4749 - Overview

• Message type: E = Error

• Message class: F4 - Line items/balances/configuration

• Message number: 749

• Message text: Caution: Before reconstruction check IMG settings (see long text)

What causes this issue?

If the Customizing settings in the credit management (Financial
Accounting) area are not correct, reconstruction (re-creation) can lead
to false data.

System Response

The system advises you to check the settings prior to a reconstruction.
The reconstruction of data can in some circumstances change documents
and therefore you should carry this out if at all possible using program
RFDKLI20 run in the background, as this may require a long runtime.

How to fix this error?

Irrespective of how you determine the credit control area (from the user
exit EXIT_SAPFV45K_001, the sales area segment or the sales organization
company code) you always need to enter a default credit control area in
table T001 (transaction OB38).
If you do not derive the credit control area (as in Releases < 4.0) from
the company code (table T001) by default, you must nevertheless still
either enter all permitted or possible combinations of company
code/credit control area (transaction OBZK) in table T001CM or maintain
the indicator in table T014 that all company codes are permitted
(transaction OB45, T014-ALLCC). This again applies irrespective of how
you determine the credit control area.
Correct maintenance of tables T001, T001CM and T014 is absolutely
essential for a reconstruction. A document containing a permitted
combination of company code/credit control area is ignored during a
reconstuction, meaning the credit control area is not changed in this
document. Where the document does not contain a permitted combination of
company code/credit control area, the latter is replaced by the default
credit control area in table T001.
CAUTION: An early check of your FI Customizing is extremely important,
as you may find that credit control areas from FI documents are
inadvertently deleted because the combination of company code and credit
control area is not permitted. Such a combination is permitted if at
least one of the three following conditions has been met:
You have set the indicator 'All company codes' in the credit control
area (T014-ALLCC, transaction OB45).
You have defined the credit control area as a default in table T001
(transaction OB38)
You have entered the combination company code/credit control area in
table T001CM (transaction OBZK).
