I have some difficulties to read this, screenshots would be really better.
in your last response you listed for example
4900000013 | 31.01.2013 | 561 | 6 | 818897 | 136482.8 | Project |
a few hours earlier the same material document was listed as:
1102 561 Q 4900000013 898 31.01.2013 1 NO
1102 561 Q 4900000013 899 31.01.2013 1 NO
1102 561 Q 4900000013 900 31.01.2013 1 NO
1102 561 Q 4900000013 901 31.01.2013 1 NO
1102 561 Q 4900000013 902 31.01.2013 1 NO
1102 561 Q 4900000013 903 31.01.2013 1 NO
The big difference between those 2 is not that you totaled 6 items, for me the big difference is that you have a Q for project stock in the single lines, while your total has no Q.
This is just an example that makes it really difficult to trust any number and to recalculate what really happened.
project Q stock is valuated in a special stock table, while normal valuated stock is visible in account view of material master which represents the MBEW table.
so you would at least need to take this apart from each other to really know the development of own valuated stock .
You started with the 351 movement in receiving plant.
I can see that 136482.83 was posted and that you listed a balance with 272965.83
but a single number cannot tell anything about development.
if you would start this report in January, then you could probably see the development.
