call the custom field from infotype 7

Hello,

Is there any operation to call the custom field from infotype 7 in time PCR.

I checked the operation hrs and table these are helpful to pick the standard field but in my case I need to pull the data from custom field.

Please advise should I need to take help from ABEper to create an custom operation to fetch the custom field from IT7 or is there any other way to get this done.

Thanks

Sachin
