Interface Determination "Not Equal" Condition is not working

Hi Team,

I am working on SAP PO 7.4 and am having in receiver determination condition. Actually I want to stop those records which are having quantity is zero. Its flat file to Idoc scenario. I tried to apply below options but no one is working.

/p1:MTPODSalesLSUK/Record_Set/Data/MTD_Quantity[not(starts-with(.,"0"))] EX

/p1:MTPODSalesLSUK/Record_Set/Data/MTD_Quantity ≠ '0'

/p1:MTPODSalesLSUK/Record_Set/Data/MTD_Quantity ≠ "0"

I see only below conditions in PO7.4.

=

≠

≈

EX

File is :

<wholesale_discount>30</wholesale_discount>

<MTD_Quantity>0</MTD_Quantity>

<MTD_avg_list_price>17.99</MTD_avg_list_price>

I have to apply condition on MTD_Quantity field.

Thanks in advance for your valuable suggestion.

Thanks,

Kumar
