[Sunilkumar3]

Main Date:

Main Asignee Name	Dispute Name	Dispute number	State Code
A	AA	1	ZA
A	BB	2	ZB
A	CC	3	ZC
A	DD	4	ZD
B	EE	5	ZE
B	FF	6	ZF
B	GG	7	ZG
C	HH	8	ZH
C	II	9	ZI
C	JJ	10	ZJ
C	KK	11	ZK
C	LL	12	ZL

Result

Main Assignee Name: A

Main Assignee Name	Dispute Name	Dispute number	State Code
A	AA	1	ZA
A	BB	2	ZB
A	CC	3	ZC
A	DD	4	ZD

So Here Main Assignee should be dynamic. In the main Data Main Assignee Name Can Increase or decrease it should show the Result. 

Main Assignee Name: B

Main Asignee Name	Dispute Name	Dispute number	State Code
B	EE	5	ZE
B	FF	6	ZF
B	GG	7	ZG
