  • Patent number: 10325276
    Abstract: Financial reporting methods and systems integrate profitability and accounting data. A universal journal entry allows user definition of relevant characteristics for a market segment. The entry appends the structure of a financial document to provide linkage to market segment characteristics. When creating the financial document including profit and loss (P&L) and balance account line items, a market segment is defined with determined characteristics stored in the line item on the basis of business process dependent rules. For example in posting information on a sales order item, sales order data may be read, and customer, product, and/or other sales order information input. Additional data can be derived on the basis of the determined master data, depending upon user needs. Embodiments allow enriched reporting (e.g., flexible market segment reporting) at the line item level, affording intuitive access to defined characteristics, e.g., drill-down into details of P&L and balance account information.

    Abstract: A commit event to a database table of a first set of database tables, of a distributed database system, can be detected. The first set of database tables can have a set of first table characteristic and the commit event can have a set of commit event characteristics. The commit event can be correlated to a database table of a second set of database tables based on the set of commit event characteristics. The commit event can be assigned a state based on the correlation of the commit event to a database table of the second set of database tables. First and second documents associated with the commit event can be generated. The second document can be based on the state of the commit event and can include adjustment information associated with the commit event and the first document.

  • Patent number: 10279424
    Abstract: A filter device for gas filtration has a filter housing and a plate-type filter element disposed in the filter housing. The filter element is provided with a raw side and a clean side and is flowed through from the raw side to the clean side by a gas to be purified in a direction that is orthogonal to a filter plane of the plate-type filter element. A cover element is connected to the filter housing by a tensioning bolt penetrating the filter element. The filter element has a cutout forming a clean-side gas collecting chamber. A sealing element is arranged on the clean side of the filter element and frames the gas collecting chamber at least partially. A sealing eye is connected to the sealing element and arranged in the gas collecting chamber, wherein the tensioning bolt is guided through the sealing eye.
