Doubts in using INNER JOIN

[Former Member]

Hi Experts,

I am working on customizing a stock summary report.

I have to output the details of Materials which are deleted in a given time period.

I have 10 select-options from 4 different tables i.e MARA, MARC, MBEW & EKPO.

I am using innner join for the same.

My doubts are:

1. Is it the best way?????

2. How do i find out the Quantity of material which was deleted???

3. Are there any tables where i can search for BUKRS(Compnay code) & WERKS(Plant) based on MATNR (Material Number)????

Hi Gaurav,

as we alll know tht using inner join is a performance issue i suggest not to use this instead use for all entries this might avoid the performance issue.

if u want to check the tables u need go to tcode se15 or se84 and give the field names and u can get the tables .

i am sending the links between the tables since u can get the exact relationships between thm....

Hi sana,

Thanks for the reply.

So now part1 and part3 of my question is answered.

Still i would like to know if which field tells me the Quanitity of Material deleted,

as i have to display the Quantity of material deleted and its value using ALV.

Can i use the Fields MENGE & VKWRT from table ISEG for the same???
