How To Fix GB305 - Impression avec & inexistante dans validation de matrice autorisée

SAP Error Message - Details

• Message type: E = Error

• Message class: GB - Messages used by the Boolean code generator

• Message number: 305

• Message text: Impression avec & inexistante dans validation de matrice autorisée

Quelle est la cause de ce problème?

You formulated a condition which is to be valuated on every line of the
table. Such conditions are not allowed in matrix validations outside of
a mathematical expression.
Included is this are, for example, expressions with field comparisons
and/or sets. These expressions cannot be processed, since the matrix
validation processes an entire table all at once. These expressions,
however, refer to exactly one line in a table.
Example:
BSEG-HKONT = "400000" not allowed
SUM ( BSEG-DMBTR ) > "100000.00" allowed
Line-by-line field comparisons are only allowed for fields that can
also be used in mathematical expressions. These expressions will be
valuated as true if they are not false for any line in the table.
Examples:
BSEG-DMBTR > "100000.00" allowed
BSEG-DMBTR = BSEG-WRBTR allowed

Le système émet un message d'erreur et ne vous permettra pas de poursuivre cette transaction tant que l'erreur n'est pas résolue.

Réponse du système

The expression is recognized as containing an error and is not
accepted.

Comment corriger cette erreur?

If you want to formulate a condition which is to be valuated per line
in the table, use the application callup point at line level. In FI,
for example, use callup point 0002 (document line).
You also have the possibility of using a user exit in which you can
either partially or entirely code your logical expression using ABAP/4.
You can find more information on user exits in <DS:DE.BOOLEXP>Boolean
