How To Fix W8198 - La valeur de type & est utilisée pour déterminer une date (type &)

W8198 - Overview

• Message type: E = Error

• Message class: W8 - Workflow: Expressions, data flow

• Message number: 198

• Message text: La valeur de type & est utilisée pour déterminer une date (type &)

Quelle est la cause de ce problème?

You are trying to assign an element of data type &v1& to an element of
data type &v2&.

Réponse du système

In cases concerning assignments, a conversion is executed at runtime
involving &v1& in &v2&, under the following rules:
N -> D,,First the conversion N -> C takes place and then C -> D.
N -> C,,The numerical field is treated like a text field,
,,,,,,leading zeros are retained.
C -> D,, the text field should contain an 8-digit date in the form
,,,,,,YYYYMMDD.

Comment corriger cette erreur?

You should ensure that only data type &V2& can be included when
calculating difference days. The necessary type conversions (MOVE) are
executed internally automatically before the arithmetic operation. For
reasons of efficiency, however, only operands of the same numeric data
type should occur within one arithmetic expression, if possible (up to
the operands for STRLEN): in such cases, no conversion is required and
special internal optimization can be carried out.
