|What happened?                                                                                    |
|    Error in the ABAP Application Program                                                         |
|                                                                                                  |
|    The current ABAP program "CL_DIAGLS_LMDB_FACTORY========CP" had to be                         |
|     terminated because it has                                                                    |
|    come across a statement that unfortunately cannot be executed.                                |
----------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------
|What can you do?                                                                                  |
|    Note down which actions and inputs caused the error.                                          |
|                                                                                                  |
|                                                                                                  |

|    Using Transaction ST22 for ABAP Dump Analysis, you can look                                   |
|    at and manage termination messages, and you can also                                          |
|    keep them for a long time.                                                                    |

|Error analysis                                                                                    |
|    An exception occurred that is explained in detail below.                                      |
|    This exception cannot be caught in the context of the current statement.                      |
|    The reason for the exception is:                                                              |
|    The program attempted to interpret the value "Z_NONSAP" as a number, but                      |
|    since the value contravenes the rules for correct number formats,                             |
|    this was not possible.                                                                        |
|                                                                                                  |
|    There is probably an error in the program                                                     |
|    "CL_DIAGLS_LMDB_FACTORY========CP".                                                           |

|How to correct the error                                                                          |
|    Whole numbers are represented in ABAP as a sequence of numbers, possibly                      |
|     with an algebraic sign.                                                                      |
|    The following are the possibilities for the representation of floating                        |
|    point numbers:                                                                                |
|      [algebraic sign][mantissa]E[algebraic sign][exponent]                                       |
|      [algebraic sign][whole number part].[fraction part]                                         |
|    For example, -12E+34, +12E-34, 12E34, 12.34                                                   |
|    If the error occurred in your own ABAP program or in an SAP                                   |
|    program you modified, try to remove the error.                                                |
|                                                                                                  |
|                                                                                                  |
|    If the error occures in a non-modified SAP program, you may be able to                        |
|    find an interim solution in an SAP Note.                                                      |
|    If you have access to SAP Notes, carry out a search with the following                        |
|    keywords:                                                                                     |
|                                                                                                  |
|    "CONVT_NO_NUMBER" " "                                                                         |
|    "CL_DIAGLS_LMDB_FACTORY========CP" or "CL_DIAGLS_LMDB_FACTORY========CM01A"                   |
