Hi,

Declaration of the variables and work area will vary for every customer. So check the coding standards of your organization.

Example as below.

Variables

Global variables

u2022 Types: GTY_XXXX

u2022 Data: GD_XXXX

u2022 Structure: GS_XXXX

u2022 Internal table: GT_XXXX

u2022 Constants: GC_XXXX

Local Variables

u2022 Types: LTY_XXXX

u2022 Data: LD_XXXX

u2022 Structure: LS_XXXX

u2022 Internal table: LT_XXX

u2022 Constants: LC_XXXX

Internal Tables

Declare Internal tables WITHOUT Header line. Use explicit work area.

Specify internal table type depending on requirement, e.g.: standard, sorted or hash.

Occurs addition is no longer allowed.

Ex.:

Data: GT_VBAP type sorted table of VBAP,

GS_VBAP type VBAP.

Regards,

Vijay V

Its up to your project naming convension standards.

Normally people will declare;

Global data which can access accross the program;

for internal tables : gt_tab or it_tab

for workareas: gw_tab or wa_tab

For Local data: which can access only in that perticula block

for internal tables : lt_tab

for workareas: lw_tab

Thanks
