conversions are said to be one time usage or one time programs but interfaces regular.if my legacy system is non sap then after interface programs a conversion program will always be required to convert the data into sap format.is it rite????

Yes it's right, but I beliebe you can insert the conversion step in the interface program.

U have to create a conversion program only if the interface is on legacy system and so in SAP you have only the file to be converted.

1) bdc is convrsion prog or interface prog

2) after i use idoc to transfer data from legacy to sap system is dere a need of any conversion program.

3) everytime data comes into sap thru interfaces , a conversion program converts it into sap format .is it rite

4) bdc is like lsmw

U need a program to convert the data only if the legacy can't give a file with the right format. So it often has to decide who has to convert the data.

The interface is the file where the data to be loaded are, i.e. the file linking the legacy to SAP, so the program reads this file is the interface.

In this situation a program can be interface and convertion program at the same time.

- 1) bdc is conversion prog or interface prog

If you use a bdc: u can run a program to convert the file to the format for the bdc program and then run this one, but you can also create a program to convert the file and then submit the bdc (so now u have only one program).

So here it depends if you need to keep separated the two steps;

- 2) Idoc needs own format file and so here it usually uses some user exit to convert the data (not the file format);

- 3) If the legacy system can't give the data in the right format, it has to convert them in the SAP, when it depends on situation;

- 4) LSMW has an interface step where the data are loaded and step where the data are converted;
