Text Determination

Hello Experts,

I am unable to copy from text data from Customer Master to SO.

I have created text id Z001 in customer master and assigned to procedure & to cust account group

Similarly created text id Z001 in SO and assigned to procedure & to doc type.

But i am unable to capture the data of Z001 which i maintained in customer master in SO.

Wat are the other settings to be done.

Kindly advise.

Thanks

Shri..
