Transaction VF31

Hi,

Requirement:-Invoice print should come in the sequence of customer.

Requirement is such that user has sorted the output of VF04 as per customer now there is an radio button name as collective billing after hitting collective billing spool is getting generated but in random as per the requirement it should be in same sequence of sorting.

Looking forward:-

Suggest me how to execute transaction VF31.

As per the other's suggestion i am trying with transaction "VF31".It is not getting executed even though i have entered correct selection criteria.

Any pointers for the same.

Regards,

Dharmesh
