How To Fix 1G638 - Suppr. en-tête non possible car il existe des postes valables

1G638 - Overview

• Message type: E = Error

• Message class: 1G - BKK: Konditionen

• Message number: 638

• Message text: Suppr. en-tête non possible car il existe des postes valables

Quelle est la cause de ce problème?

You cannot delete the selected header because there are still positions
in the condition whose <ZK>Valid From</> date (after the deletion) is
before <ZK>Valid From</> date of the header.

Comment corriger cette erreur?

Delete the corresponding condition position and continue with the
deletion of the header.
When the principle of dual control is activated, the deleted condition
position must already be released. A condition position deletion that
has not yet been released is seen as still existing.
