Hi,
Thanks for reply.
Dat aprovider 1 cust, no, product no, various dimensions
Data provider 2 cust no, product no, issue no, measures
Dat provider 3 cust no, product no, various unlinked dimensions,
Understand we need to link the cust no and product no dimesnions between all three by merging but differing number of the rows in each block
If have a block with cust no and product no in it but query 3 has several rows for the cust/product no combination.
e.g cust 100 , product no 700 data provider 1 1 row, data provider 2 10 rows as 10 issues
data provider 3 returns 4 rows
Thanks
