Hello Ramana,
Hence, for every record in MSEG or MBEW there should be a MARA record. Even if I assume that there is some remote chance of this happening, you can use left outer join connection MSEG and MBEW to AT_MARA in the analytic view (just like you intend to do in the calculation view). This way, all records of MSEG and MBEW are aggregated, irrespective of corresponding material master data in MARA. As a side note, it is not advisable to use attribute views in the joins of calculation views. The filter may not push down and can cause performance issues.
Hope I understood your issue correctly.

Yes that is correct but I want sum of quantity only for those which satisfies AT_MARA view records.
say in MARD(AT_MARA) ,I have a filter which can lead to filter out that material.
This way, all records of MSEG and MBEW are aggregated, irrespective of corresponding material master data in MARA.
In this case the materials for which there is no entry in MSEG OR MBEW will be left.
thats why i am using again AT_MARA to display all the materials whether they have entry in MSEG or not(Zero quantity).
