Diagnosis
In parameter INOUT_NEXT_MATNR, material number &V1& was transferred asthe starting point. This material number, however, is not contained intable INOUT_MATNR_TAB. Normally, this inconsistency should not occur ifthe values are transferred to INOUT_NEXT_MATNR and INOUT_MATNR_TAB insubsequent calls as they were returned in previous calls of thefunction module.

Procedure
Find out how an incorrect material number was saved in parameterINOUT_NEXT_MATNR. During the first call, the function module waspossibly called without using the initial parameter INOUT_NEXT_MATNRwithin a sequence of blocked calls.
