Dear
I am asking second filter formula.
Formula me Kya likhe.

Jo awbbill used ho gya ho vo list me show na ho.

 

wo kaha use huaa hai ye kaise pata hoga...

 

Suppose
Two udf hai.
Udf1 udf 2
Udf 1 vo udf hai jo coll table me hai.
Fomate: udf1 ( list of all AWB bills)

Second udf vo hai jahan hun show table kar ke awbbill save karte hai.
Ab jo awbbill no udf1 or udf2 dono me ho vo awb bill list se hat jaye...
I think Mai samjha paya hun

 

Filter ka formula mei kya code diya hai

 

[

[ sys: formula]
Awbfilter: $shipper=#EI CONSIGNEE

YE DIYA KAAM HO GAYA...
