Found problem on archieving Material Document (Object: MM_MATBEL) as below -

After inputting the following 4 Mat docs. in "Write" variant and executing in "Test Mode",

Found only two Mat docs. in the log. The Mvt Type of these two Mat docs. is 601.

Even if inputting the two missing Mat docs. only in the "Write" variant to test archieving, no detailed log was found as below. The Mvt Type of these two Mat docs. is 101.

Could you advise reason & how to solved this problem ?

Tks,

KH Fong
