Hi All,

I have few questions please anyone give the answer.

1. As we know that the internal table having the type:Standard,sorted and hashed type and performance wise hashed table having the high performance intead of this why we always use standard table?

2.we always use ST05,SE30 for check the performance of program is there other way for checking the performace?

3.what are the ways of finding the userexit instead of program--customer-function and CMOD-SAP Enhancement??

Please give me the answer of these question.

Thanks & Regards,

Meenakshi

Hi,

You can find user exits y using tables MODACT and MODSAP tables. These tables are in return associated with CMOD and SMOD transactions.

You can find sample code through which you can find userexits in a transaction.

Hi,

1. Regarding Internal Tables:

Hash table has the hash algorithm associated with it. So irrespective of the no. of entries this hash algorithm is always computed to insert an element into the hash table. If the no. of entries are large enough then it is ok to use the hash table or else we have to pay the penalty for this algorithm when there is a small data set.

Standard table doesnt require these type of algorithms. Simply the values are inserted as it comes. So for small data set it is good to use standard table.

2. check this link for code inspection:

3. Go the SAPIMG (SE81). Select the area you want to find user exit ( like logisitcs.. etc). Then click SAPIMG button. It will take you to repository information browser. Then click search. U vl find all the user exits of the corresponding area u r looking for.
