\"SAP\"In this step-by-step guide I’d like to show you how to create an application log which can be easily extended with your extra fields containing additional information.\u00a0To maintain and access application logs using SAP standard you can use transaction codes SLG0 (add\/edit\/delete application log) and SLG1 (standard application log viewer).<\/p>\n

Create application log<\/h1>\n

We will create our application log using transaction SLG0<\/em> and we will call it ie ZTEST<\/em>.<\/p>\n

\"Application<\/a><\/p>\n

Now we create a Subobejct<\/em> called ie EXT_FIELDS<\/em><\/p>\n

\"Application<\/a><\/p>\n

Now the application log storage area is prepared so we can start creating logs.<\/p>\n

DDIC Structure for extra fields<\/h1>\n

Run transaction SE11\u00a0and create new structure which will hold the additional data we would like to display in application log – one field in the structure per column in the appication log.<\/p>\n

ABAP program<\/span><\/p>\n

Run transaction SE38<\/em>\u00a0and create new program called ie\u00a0Z_APPLOG_EXT_FIELDS.\u00a0<\/em><\/p>\n
