Checking table existence using Class and it’s method in SE11 without using FM in ABAP

To perform this without using Function module, you can use class- “cl_rebf_ddic_tabl”. Note that Class methods are almost similar to function modules. They are defined as code blocks to perform specific functionality.

Example

Try using below code: 

CALL METHOD cl_rebf_ddic_tabl=>exists
EXPORTING
   id_name = [table name]
   id_tabclass = 'TRANSP' " For table
   * if_noview = ABAP_FALSE
      receiving
      rf_exists = yes

   . 

This will return “X” if the table exists in Transaction SE11.

CALL METHOD CL_REBF_DDIC_TABL=>methodname EXPORTING/IMPORTING
GET_TEXTTAB - Supplies the Corresponding Text Table
GET_COMPLETE - Supplies All Technical Information
GET_DETAIL_X - Supplies Extended Header Data
GET_FIELD_LIST - Supplies the Field List
GET_FIELD_LIST_X - Supplies the Field List with Additional Data
GET_RUSER - Supplies Author/Date/Time of Last Change
COMPARE_WITH_DATA - Detail Comparison
PUT_COMPLETE - Creates a New Table/Structure
SPLIT_FIELDNAMES - Generates Field List According to List
EXISTS - Table/Structure Available?
EXISTS_FIELD - Field Available in Table/Structure?
EXISTS_INDEX_FOR_FIELDS - Field Available in Table Index?
