hi satish,

1) what is the Difference between UPLOAD and WS-UPLOAD?

ans)Ws_upload is the advanced version of the upload function module. In ws_upload file type parameter is predefined as ASCII and it has more exceptions as compare to the upload function module.

2)what is the Difference between UPLOAD and GUI-UPLOAD?

ans)The functionality is similar to that of function module WS_UPLOAD. The difference is that the DataProvider is used for the upload instead of GMUX.

3)What is BDC table?

ans) The recording of a transcation we do in SHDB is stored in BDCDATA internal table.It stores all nformationlike screen number, screen type etc.

4)Difference between Synchronous and Asynchronous update in call transaction?

ans)In synchronous method incase if there is any change in the table all the related tables will be changed accordingly and then sy-subrc will be returned.In asynchronous method in case if there is any change in the table the s-subrc will be immediatel returned and then the related tables will be updated. the diffrence between these two is in asynchronous even if the related tables are not updated the sy-subrc will still be returned as 0.

Hope this is helpful, Do reward.

1. The diffrence between WS_Upload and Upload is when you use function Upload it prompts for a dailog box where in you need to key in the file location.Where as in case of WS_Upload you specify the file location in the function input parameters itself.

2. UPLOAD does not require the Filename and Filetype to be exported to the function, instead it will ask for the same at the runtime. However for GUI_UPLOAD, these two parameters need to be passed. GUI is similar to WS Upload but no confrmation is given.

3. BDC Table is the internal table used in the program which Converts the User required functionality to the format which system understands (Screen Numbaer, Screen Name, Screen Flow, Field Name and Field Value)

4. S is for Synchronous update in which if you change data of one table then all the related Tables gets updated. And sy-subrc is returned i.e., sy-subrc is returned for once and all.

A is for Asynchronous update. When you change data of one table, the sy-subrc is returned. And then updating of other affected tables takes place. So if system fails to update other tables, still sy-subrc returned is 0 (i.e., when first table gets updated).

5. Local Files are stored in Presentation Server while Sequential Files are stored in Application Server

Upload or Download of Local files is done in a single shot while for the Sequential Files, the data has to read or Transferred, Line by Line or character by character depending upon the mode
