Parameter Transaction

Former Member — Wed, 23 Feb 2005 13:44:44 GMT

Hi All,

I have created a Parameter transaction for SM30 by which I am able to maintain entries in my user-defined table. But, I would like to restrict the entries displayed (not using the conditions in SM30) by creating the selection screen where only the few fields of the user-defined table are presented for selection and based on that I get output. I want the full functionality of the parameter transaction(creation , deletion of the entries) though.

if some one has any ideas kindly let me know.

Thanks,

Manish

You may "customize" your table maintenance function group to your specific needs. But, in doing this, realize that if you need to re-generate it, your changes will be over written.

You could also build your own table maintenance program

Have you tried maintenance type: 2 step so that you can get a selection type screen? If so, what do you not like about it?

Hi Manish,

I don't know if a two-step maintenance is good for you as suggested in one reply here, but if your requirement is to give user a SM30 feature but have a selection screen of your own, then here is an example of how you can achieve that with a custom program. I don't think you can achieve that with just parametric transaction and without using conditions and without modifying the maintenance screens.

Let me know if you have any questions regarding this code. This program is for a Z table mainetnance which has two fields, a code and a description. Users are given a choice of entering their criteria for either the code or the description or both. This criteria is internally converted to a format that the table maintenance function module understands. The result is that users get to see and maintain only the records that they wanted.
